Description

Technical Field

[0001] The present invention belongs to the technical field of rolling smoothness testing devices, and more specifically, relates to a rolling smoothness testing device for industrial caster production. Background Art

[0002] A caster is a steerable mobile device formed by combining a wheel axle and a bracket, and its core structure includes a wheel body, a rotary bearing, a steering bracket, and a braking component. Due to its ability to freely rotate 360° (swivel caster) or its directional movement characteristics, such devices are widely used in fields such as logistics transportation, medical devices, industrial equipment, and furniture. For example, supermarket shopping carts achieve flexible steering through four sets of casters, hospital beds complete smooth movement with the help of silent casters, and heavy-duty storage shelves rely on high-load casters for position adjustment.

[0003] In industrial scenarios, the rolling performance of casters directly affects the equipment movement efficiency and operation safety. The rolling smoothness, as a key performance indicator, is specifically manifested as: the starting resistance coefficient of the wheel body under a load state and the friction force fluctuation value during uniform motion. When the smoothness does not meet the standard, it may lead to equipment movement jams (such as path deviation of AGV handling robots), abnormal wear (such as premature failure of the bearings of production line conveyor racks), or even safety accidents (such as out-of-control displacement of hazardous chemical storage tanks).

[0004] Traditional testing methods mostly adopt the manual push-pull testing method, that is, operators evaluate the smoothness of caster movement through physical sensation. This method has obvious defects, such as the subjective evaluation lacking a quantitative standard and the test results being affected by the physical differences of operators; and the problem of low manual testing efficiency. Therefore, developing an automated testing device with multi-dimensional detection capabilities is of great value for improving the accuracy of product quality control and reducing after-sales failure rates. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a rolling smoothness testing device for industrial caster production that can overcome or at least partially solve the above problems.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: a rolling smoothness testing device for industrial caster production, including a rotating disk rotatably connected to a mounting table, and further including: a clamping station, a plurality of which are circumferentially arranged on the rotating disk for clamping caster parts; an accelerating wheel that can move horizontally; a testing wheel provided with a force sensor; a pressing plate for simulating a load and an N-shaped push rod that is linked when providing a load, the pressing plate is linked with the testing wheel and the N-shaped push rod to simulate the load condition of the caster part in the test state and the rotation condition in the steering state; a discharging air cylinder for disengaging the caster part from the clamping station.

[0007] Preferably, the clamping station includes a bottom plate installed on a rotating disk. On the bottom plate, a first rod and a second rod are symmetrically arranged respectively. On the bottom plate, sliding grooves are symmetrically formed. The end of the second rod is connected to the bottom plate through a first spring, and the second rod slides in the sliding groove.

[0008] Preferably, a connecting frame is installed on the installation table. A sliding seat is slidably connected to the connecting frame. The sliding seat is driven to move horizontally by a pulling cylinder. A motor is installed on the sliding seat, and the acceleration wheel is installed on the output end of the motor. A limiting clamp is slidably connected to the sliding seat through a second spring, and the limiting clamp corresponds to the front wall on the caster assembly.

[0009] Preferably, it further includes a mounting frame installed on the connecting frame. A connecting seat is slidably connected to the mounting frame through a guide rod. A third spring is sleeved on the guide rod, and the test wheel is rotatably connected to the connecting seat.

[0010] Preferably, an electric sliding table is installed on the mounting frame. A connecting plate is installed on the electric sliding table. Slide rods are symmetrically and slidably connected to the connecting plate. The pressing plate is installed at the end of the slide rod, and a fourth spring is connected between the connecting plate and the pressing plate.

[0011] Preferably, a first wedge-shaped block is installed on the connecting plate, and the first wedge-shaped block corresponds to the connecting seat.

[0012] Preferably, it further includes a mounting block installed on the bottom plate. The N-shaped push rod is rotatably connected to the mounting block through a second torsion spring. A second wedge-shaped block is installed on the connecting plate, and the second wedge-shaped block corresponds to the tail end of the N-shaped push rod. The front end of the N-shaped push rod corresponds to one side of the steering seat on the caster assembly.

[0013] Furthermore, a cushion block and an inclined block are respectively and fixedly connected to the first rod and the second rod.

[0014] Furthermore, a first material separation plate and a second material separation plate are respectively arranged on the installation table. The unloading cylinders are respectively installed on the installation table at the positions of the first material separation plate and the second material separation plate. A through hole is formed between the symmetric second rods on the bottom plate close to the bottom plate. The telescopic end of the unloading cylinder corresponds to the through hole.

[0015] Furthermore, the first rod is rotatably connected to the bottom plate through a first torsion spring. A stop block is fixedly connected to the bottom plate on the side of the first rod close to the second rod. The stop block is used to limit the rotation angle of the first rod.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: This device can continuously and batchwise test the rolling smoothness of casters, and respectively test the rotational resistance of casters in the idling state, load state, and steering state.

Its design takes into account efficiency, precision, and reliability, can significantly improve the production quality control level, and is suitable for the quality control requirements of large-scale caster production;

[0017] When this device tests the idling state, load state, and steering state of casters, it only needs to control the lifting of the connecting plate to complete the tests of the idling state, load state, and steering state at one time, thereby effectively improving the automation degree of the test, reducing manual intervention operations, and reducing the use of electrification equipment, and improving the reliability and stability of the test;

[0018] The clamping station can not only facilitate the clamping of casters, but also facilitate the rapid unloading of casters during unloading. The automated material separation and unloading process reduces manual operations, improves the test efficiency, and reduces the production cost.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] The following combines the attached Figure 1 - attached Figure 11 drawings to detail the technical solutions provided by each embodiment of the present invention.

[0035] Embodiment 1: Refer to Figures 1 - 10, a rolling smoothness test device for industrial caster production, including a rotating disk 1 rotatably connected to a mounting table 7, and also including: a clamping station, a plurality of which are arranged on the rotating disk 1 for clamping a caster member 2; a horizontally movable acceleration wheel 33; a test wheel 47 provided with a force sensor 48; a pressure plate 52 for simulating a load and an N-type push rod 120 which is linked when providing a load, the pressure plate 52 and the test wheel 47 and the N-type push rod 120 are linked to each other to simulate the load condition of the caster member 2 in the test state and the rotation condition in the steering condition; a discharge cylinder 13 for disengaging the caster member 2 from the clamping station;

[0036] The clamping station includes a bottom plate 11 mounted on the rotating disk 1, on which a rod 1 111 and a rod 2 115 are symmetrically arranged, and a slide groove 114 is symmetrically opened on the bottom plate 11. The end of the rod 2 115 is connected to the bottom plate 11 through a spring 116, and the rod 2 115 slides in the slide groove 114;

[0037] When the device is in use, the slot 20 on the mounting plate 21 of the caster member 2 is first inserted into the rod 2 115, and then pulled toward the direction close to the rod 1 111. Since the rod 2 115 is connected to the base plate 11 through the spring 116, the spring 116 will be compressed to store force when pulled. When the other two slots 20 on the mounting plate 21 are aligned with the rod 111, the mounting plate 21 is inserted into the rod 1 111, so that the caster member 2 is clamped on the base plate 11 under the thrust of the spring 116. Therefore, the clamping station can effectively and quickly clamp and limit the caster member 2 to avoid falling during the test. The mounting of the caster member 2 can be operated manually.

[0038] The rotating disk 1 is driven by a motor device to rotate intermittently. When the caster 2 clamped on the clamping station moves to the position opposite to the acceleration wheel 33, the rotating disk 1 stops rotating. Then the acceleration wheel 33 is driven by the motor 32 to rotate and approach the caster 2. When the acceleration wheel 33 contacts the rotating wheel 23 on the caster 2, the acceleration wheel 33 drives the rotating wheel 23 to rotate. Then the acceleration wheel 33 moves away from the rotating wheel 23, and the rotating wheel 23 rotates by itself.

[0039] When the acceleration wheel 33 moves away from the rotating wheel 23, the test wheel 47 approaches and contacts the rotating wheel 23, so that the rotating wheel 23 drives the test wheel 47 to rotate. At this time, the force sensor 48 on the test wheel 47 monitors the rotation speed of the test wheel 47, and the computer generates a resistance curve of the rotating wheel 23.

[0040] When the smoothness of the rotation of the rotating wheel 23 is not a problem, the resistance curve tends to be flat;

[0041] When there is a problem with the smoothness of the rotation of the rotating wheel 23, such as a large rotational damping, the corresponding resistance curve will have a significant decline or shift;

[0042] The resistance curve measured thereby will be compared with the threshold value set in the computer, and then it can be determined whether the measured caster member 2 meets the quality and process requirements.

[0043] During the process of the test wheel 47 contacting the rotating wheel 23, the pressing plate 52 will press down on the rotating wheel 23 from top to bottom to achieve the smooth rolling of the caster member 2 under the load state. The test wheel 47 will conduct a test to obtain the resistance curve, which will be compared with the set threshold value.

[0044] When the pressing plate 52 applies force to the rotating wheel 23, it will be linked to cause the N-shaped push rod 120 to push the caster member 2 from one side of the caster member 2, so that the swivel base 22 of the caster member 2 rotates on the mounting plate 21, so as to simulate the working condition of the rotating wheel 23 rotating during the rotation of the caster member 2.

[0045] After the test is completed, the caster member 2 is moved away from the position where the acceleration wheel 33 is located, and the caster member 2 is removed from the clamping station by the unloading cylinder 13.

[0046] Therefore, this device can continuously and batch-wise test the smooth rolling degree of the caster member 2, and respectively test the rotational resistance of the caster member 2 in the idling state, load state, and steering state. Through the monitoring of the force sensor 48, it can avoid the subjective errors of traditional manual testing. Through automated transfer, multi-condition simulation, high-precision sensing and data analysis, it realizes the all-round and efficient detection of the rolling performance of the caster member 2. Its design takes into account efficiency, precision and reliability, can significantly improve the production quality control level, and is applicable to the quality control requirements of large-scale caster member 2 production.

[0047] Example 2: Refer to Figures 1 - 10 , a rolling smoothness test device for industrial casters, which is basically the same as Example 1. Further: A connecting frame 3 is installed on the mounting table 7, a sliding seat 31 is slidably connected to the connecting frame 3, the sliding seat 31 is driven by a pulling cylinder 30 to move horizontally, a motor 32 is installed on the sliding seat 31, an acceleration wheel 33 is installed on the output end of the motor 32, a limiting clip 34 is slidably connected to the sliding seat 31 through a second spring 35, and the limiting clip 34 corresponds to the front wall 24 on the caster member 2.

[0048] It further includes a mounting frame 4, a connecting seat 44 is slidably connected to the mounting frame 4 through a guide rod 45, a third spring 46 is sleeved on the guide rod 45, and a test wheel 47 is rotatably connected to the connecting seat 44.

[0049] An electric sliding table 41 is installed on the mounting frame 4, a connecting plate 42 is installed on the electric sliding table 41, sliding rods 5 are symmetrically slidably connected to the connecting plate 42, a pressing plate 52 is installed at the end of the sliding rod 5, and a fourth spring 51 is connected between the connecting plate 42 and the pressing plate 52.

[0050] A wedge block one 43 is installed on the connecting plate 42, and the wedge block one 43 corresponds to the connecting seat 44.

[0051] It further includes a mounting block 12. The N-shaped push rod 120 is rotatably connected to the mounting block 12 through a torsion spring two 123. A wedge block two 6 is installed on the connecting plate 42, and the wedge block two 6 corresponds to the tail end 121 of the N-shaped push rod 120. The front end 122 of the N-shaped push rod 120 corresponds to one side of the steering seat 22 on the caster assembly 2.

[0052] The specific implementation method for performing the rotational resistance test in the idle state, load state, and steering state is to pull the cylinder 30 to push the slide block 31 to make the acceleration wheel 33 approach the runner 23 on the caster assembly 2. The limit clamp 34 on the slide block 31 contacts the front wall 24 of the steering seat 22 on the caster assembly 2. The V-shaped slot of the limit clamp 34 is clamped into the front wall 24 to limit the steering seat 22. Subsequently, the acceleration wheel 33 contacts the runner 23 on the caster assembly 2, and then the runner 23 can be driven to rotate through the acceleration wheel 33;

[0053] When the pulling cylinder 30 pulls the slide block 31 away from the runner 23, the electric slide table 41 drives the connecting plate 42 to move downward. During the downward movement of the connecting plate 42, the inclined wall of the wedge block one 43 contacts the connecting seat 44 and pushes the connecting seat 44 to slide on the connecting plate 42, squeezing the spring three 46, so that the test wheel 47 approaches and contacts the runner 23. At this time, the straight wall of the wedge block one 43 contacts the connecting seat 44;

[0054] When it is necessary to apply a load to the runner 23 through the pressure plate 52, the electric slide table 41 is continued to drive the connecting plate 42 to move downward, so that the pressure plate 52 contacts the runner 23, and the pressure plate 52 squeezes the spring four 51 to realize pressing down on the runner 23.

[0055] When the connecting plate 42 is continuously driven to move downward, the pressure plate 52 continues to apply a load to the runner 23, and the load increases. At this time, the wedge block two 6 abuts against the tail end 121 of the N-shaped push rod 120, causing the N-shaped push rod 120 to rotate, so that the front end 122 of the N-shaped push rod 120 abuts against the side surface of the steering seat 22 of the caster assembly 2, thereby realizing a small-angle rotation of the caster assembly 2;

[0056] It should be understood that the height of the N-shaped push rod 120 is lower than that of the test wheel 47. Therefore, when the clamping fixture with the caster assembly 2 is moved to the connecting frame 3, the N-shaped push rod 120 will not collide with the test wheel 47.

[0057] Therefore, when the caster member 2 is tested for its idling state, load state, and steering state, the present device only needs to control the lifting of the connecting plate 42 to complete the tests of the idling state, load state, and steering state at one time, thereby effectively improving the degree of automation of the test, reducing manual intervention operations, reducing the use of electrical equipment, and improving the reliability and stability of the test.

[0058] The electric slide table 41 can accurately control the downward movement stroke of the connecting plate 42, making the pressing load of the pressing plate 52 on the runner 23 more accurate.

[0059] Embodiment 3: Refer to Figures 4 - 7 , Figure 11 , an industrial caster production rolling smoothness test device, which is basically the same as Embodiment 1. Further, a cushion block 117 and an inclined block 118 are respectively fixedly connected to the first rod 111 and the second rod 115;

[0060] A first material distribution plate 8 and a second material distribution plate 9 are respectively arranged on the mounting table 7, and the unloading cylinders 13 are respectively installed on the mounting table 7 at the positions of the first material distribution plate 8 and the second material distribution plate 9. A perforation is opened on the bottom plate 11 near the symmetric second rods 115, and the telescopic end of the unloading cylinder 13 corresponds to the perforation;

[0061] The first rod 111 is rotationally connected to the bottom plate 11 through a first torsion spring 112, and a stop block 113 is fixedly connected to the bottom plate 11 on the side of the first rod 111 close to the second rod 115.

[0062] The first rod 111 is in a state of tilting downward at the top in the initial state (refer to Figure 11 ), when the caster member 2 is clamped on the bottom plate 11, by orienting the bottom surface of the mounting plate 21 of the caster member 2 towards the first rod 111, aligning the slot 20 on the mounting plate 21 with the front end of the first rod 111 and sleeving it, then flipping the caster member 2, and sleeving the other slots 20 on the second rod 115. At this time, the first torsion spring 112 on the first rod 111 is in a state of storing energy;

[0063] Moreover, since the inclined block 118 is installed on the second rod member 115, the casters 2 located on the bottom plate 11 are inclined towards the outer periphery of the rotating disk 1. Since the steering seat 22 of the caster 2 is eccentrically arranged, the rotating wheel 23 is biased towards the mounting plate 21 side. Therefore, by providing the inclined block 118 on the second rod member 115, the center of gravity of the rotating wheel 23 can be deviated towards the outer periphery of the rotating disk 1. Further, when the caster 2 moves to the acceleration wheel 33, it is further convenient to align the front wall 24 of the steering seat 22 with the V-shaped slot of the limit clamp 34, and it is further convenient for the limit clamp 34 to limit the steering seat 22, facilitating the contact between the acceleration wheel 33 and the rotating wheel 23. It should be understood that the limit clamp 34 is slidably connected to the sliding seat 31 through the second spring 35. Therefore, when the N-shaped push rod 120 pushes the caster 2, the limit clamp 34 will adaptively slide towards the sliding seat 31, so it will not hinder the small-angle rotation of the caster 2.

[0064] When the caster 2 is tested and the caster 2 is a qualified product after the test, when the caster 2 after the test pauses at the second distribution plate 9, the telescopic end of the unloading cylinder 13 located at the second distribution plate 9 extends into the through hole of the bottom plate 11, so that the telescopic end of the unloading cylinder 13 abuts against the bottom surface of the mounting plate 21 of the caster 2. And since the telescopic end of the unloading cylinder 13 is close to the mounting plate 21 side, when the telescopic end of the unloading cylinder 13 pushes the mounting plate 21 upward, the mounting plate 21 will first disengage from the second rod member 115. When the mounting plate 21 loses the restriction of the second rod member 115, the stressed first rod member 111 will drive the caster 2 to flip and then fall onto the second distribution plate 9.

[0065] Similarly, when the caster 2 is unqualified in the test, at the first distribution plate 8, it is pushed by the unloading cylinder 13 located at the first distribution plate 8 and pushed onto the first distribution plate 8.

[0066] Therefore, in this embodiment, the clamping station can not only facilitate the clamping of the caster 2, but also facilitate the rapid unloading of the caster 2 during unloading. The automated material distribution and unloading process reduces manual operation, improves the test efficiency, and reduces the production cost.

[0067] In the present invention, when testing the caster 2 in the idle state, load state, and steering state, only by controlling the lifting of the connecting plate 42, the tests in the idle state, load state, and steering state can be completed at one time. Furthermore, the degree of automation of the test is effectively improved, and manual intervention operation and the use of electrification equipment are reduced, improving the reliability and stability of the test. Compared with the prior art, the subjective error of traditional manual testing is avoided. Through automated transfer, multi-condition simulation, high-precision sensing and data analysis, a full-range and efficient detection of the rolling performance of the caster 2 is realized. Its design takes into account efficiency, precision and reliability, can significantly improve the production quality control level, and is applicable to the quality control requirements of large-scale caster 2 production.

[0068] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention, without departing from the scope of the technical solution of the present invention, may make some changes or modifications using the technical content prompted above as equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention's solution.
